Chapter 394: Gilding (3)
As I approached the liquid that had dripped onto the iron rod and examined it in response to Hwa-eun’s explanation, I became convinced—this was sulfuric acid.
A colorless, odorless substance that corrodes metal.
Eyes lighting up, I asked about something else.
Only one final ingredient remained now.
“Then... could I possibly get my hands on some saltpeter?”
At that, both Hwa-eun and her grandfather turned to each other with utterly baffled expressions.
As if I had just said something completely absurd.
Seeing their faces, I had a sudden feeling that this might not be easy to obtain.
What the— Is it classified as a strategic material or something? I thought fireworks powder was made and sold all over the Central Plains without much regulation. There was a ridiculous loophole in the counterfeit coin plan that let me slide through, but this is where I hit a wall?
I had gotten through the counterfeiting scheme so smoothly, and now—ironically—I was hitting a wall trying to get saltpeter, which I thought would be simple.
Saltpeter. Potassium nitrate.
Since it’s used to make gunpowder, maybe it’s under government control.
